Separate the events based on the sign of sin(φ).

Question

Dear Experts
I have generated the process Z → e⁺ e⁻ μ⁺ μ⁻ using MadGraph, and I obtained an unweighted_events.lhe file. After that, I successfully installed MadAnalysis5.
Now I am stuck. I entered the MadAnalysis5 environment using the commands:
cd madanalysis5
./bin/ma5
But I donot t know how to connect the MadGraph events to MadAnalysis5.
My goal is to analyze the events and separate them based on the sign of sin(φ), where φ is the azimuthal angle of the momentum (as defined in Table 14 of arXiv:1206.1599).

I am still new to MadAnalysis5, and I find the procedure a bit confusing. Any guidance or example on how to import my LHE file into MadAnalysis5 and apply such an angular selection (sinφ > 0 and sinφ < 0) would be greatly appreciated.
Best regards,

Hi, I would suggest to have a look at our wiki page where you can find tutorials, a manual and reference cards. This should provide enough documentation to answer all the questions in your message. Regards, Benjamin
